A fire at a popular bar in Wasaga Beach was intentionally set, police believe.

Emergency crews were called on Tuesday night after smoke was seen coming out of the rear of the Banana Beach Club.

A search of the building led investigators to materials, which they believe, were used to start the fire. A special hazmat unit had to be brought in to remove the items.

The investigation is ongoing and anyone with information is asked to call police or Crime Stoppers.
